Full textThe surface treatment (ST) industry is currently undergoing major upheavals, particularly concerning environmental aspects, due to increasingly stringent standards. ST uses large volumes of water and chemicals in its manufacturing processes and its wastewater is acknowledged as being among the most polluting. The main environmental problem facing ST plants is the high pollution load of the effluent they generate. In this thesis, we analyzed and optimized three physicochemical units for the treatment of ST industrial wastewaters. We present the abatements obtained in the levels of pollution after the various chemical optimizations validated in the laboratory and then transposed to the industrial site. To evaluate the utility of each optimization proposal, bioassays using three bioindicators (Daphnia magna, Gammarus pulex, Lactuca sativa) were also carried out on the effluents of the treatment plants. The results showed that discharge waters were characterized by a polycontamination, organic and metallic, highly variable in time. These effluents also presented a high toxicity towards the bioindicators studied. Bioassays confirmed the preponderant role of metal in the toxicity. The optimization of the station and chemical treatment proposed reduced the organic load and the concentrations of metals. Decreasing pollutant concentrations in the wastewaters led to a significant reduction of their toxicity on the three bioindicators. This demonstrates that there is a relationship between “chemical efficiency” and “reduction of environmental impact”

Full textThis PhD thesis is dedicated to nonlinear system modelling using Volterra series and to Volterra model inversion in order to restore quantities which are not directly measurable. First chapter is about parsimonious modelling for nonlinear systems. In order to limit the global number of parameters Volterra kernels are expanded on transfer functions instead of generalized function bases, and Volterra model static part is separated from its dynamic part. Second chapter deals with Volterra model inversion. First, we use Tikhonov's regularization method, then we propose two inversion methods using restored input feedback. In order to reduce the necessary computational burden for Tikhonov regularization, we suggest a Volterra model discretization combined with optimization and simulation procedures performed on a sliding window. In third chapter, modelling and inversion methods are put into practice with a chemical process, and a biological process

Full textRemediation of soils contaminated by persistent organic pollutants like Polycyclic Aromatic Hydrocarbons (PAHs) have been widely developed after the discovery of thousands of contaminated sites all over the world. Among the organic pollutants, PAHs are considered as biorefractory compounds, relatively immobile in soils, toxic, carcinogenic and mutagenic. Several techniques have been studied to remove these pollutants from soils, as the Advanced Oxidation Processes (AOPs) that have been proposed in recent years. AOPs are considered as an attractive alternative able to clean up matrices contaminated by refractory substances. In this work, AOPs have been studied to assess their efficacy in the oxidation of PAHs contained in four soil samples from Brazil and France. These AOPs were: (i) treatment by Fenton reactant (H2O2 and Fe(II), (ii) Fenton-like reactant, i.e. Fenton reactant without Fe(II) addition, considering that naturally occurring minerals provided Fe(II), (iii) and (iv) the same treatment with UV radiation, so-called photo-Fenton and photo-Fenton like reactions, and eventually (v) potassium permanganate. In each case, the optimal conditions were determined following factorial designs. Moreover, treatment selectivity was investigated, comparing the oxidation of lower and higher molecular weight PAHs. The formation of oxidation by-procducts was also assessed. To finish, the quality of treated soils was evaluated, by measuring the physico-chemical properties and above all by germination and growth experiments with ray grass chosen as a model plant. The objective was to assess if the treatments allowed further revegetation. In all cases, good oxidation results were reached. Concerning the evaluation of soil quality, it was shown that the treatment by KMnO4, was not compatible with further revegetation. Fenton’s reactant had a good effect on soil quality for further revegetation
Remediação de solos contaminados por poluentes orgânicos persistentes tem merecido destaque devido a descoberta de milhares de áreas contaminadas em todo mundo. Dentre os poluentes orgânicos, que merecem atenção encontram-se os hidrocarbonetos políciclicos aromáticos (HPAs) pois são compostos recalcitrantes, relativamente imóvel no solo, tóxicos, carcinogênicos e mutagênicos. Várias técnicas vêm sendo estudada a fim de remover estes poluentes dos solos podendo citar atualmente os Processos Oxidativos Avançados (POAs). Os POAs trata-se de um tratamento alternativo capaz de degradar das matrizes contaminadas por substâncias refratárias. Neste trabalho, os POAs têm sido estudado para avaliar seu comportamento na oxidação dos HPAs em quatro diferentes tipos de solo, originados do Brasil e da França. Avaliou-se como esses processos se comportam em relação a uma antiga e recente contaminação, bem como avaliar a existência da seletividade em relação aos HPAs de baixo e alto peso molecular e identificar a possibilidade de formação de intermediários de oxidação. Também pretende-se analisar a qualidade do solo após o tratamento visando avaliar se este solo pode ser revegetalizado ou torna-se inerte. Os POAs que aplicados nestes solos foram: Reagente de Fenton, Reagente Fenton-like, Reagente Foto-Fenton empregando-se a radiação natural e artificial, Reagente Foto-Fenton like e Permanganato de Potássio. De uma maneira geral, resultados satisfatórios foram alcançados em todos os solos estudados para a oxidação dos HPAs pelos POAs. Em relação a avaliação da qualidade dos solos da França após aplicar os POAs , o tratamento por Permanganato de Potássio não foi compatível com o processo de revegetalização. Já o tratamento por reagente de Fenton foi compatível ao processo e ainda observou uma melhora no crescimento das plantas quando comparado ao solo contaminado

Full textThe aim of the study is to evaluate to what extend the treatment of salted liquid waste can be improved by the integration of electrodialysis upstream the biological step. Firstly, a theoretical approach of the different phenomena involved in electrodialysis was used to provide relationships between the characterise parameters of the mass transfer, the operating parameters and the composition of the fluid to be treated. More over, the influence of the mineral ions hydration on the transfer coefficient of the organic matter was emphasized. In this manner, the general character of the solvatation effect, observed with different species, membranes and driving force, was demonstrated. Secondly, we have studied the influence of the ionic composition on the biological activity, characterized by the micro-organisms growth rate. Results have showed the existence of a limit concentration value, above which the specific growth rate decreased. This concentration, which depends on the salt nature, corresponds to an osmotic pressure only value. The demineralisation factor to be reach by the electrodialysis step corresponds to this osmotic value in order to have an optimum biodegradation. Finally, the methodology pointed out with synthetic model waste was validated with an industrial waste

Full textThe modeling, simulation and optimization of different industrial wastewater treatment processes using the process coupling method were studied in order to compare their purification performances and to evaluate the associated energy and economic expenses. Three effluents characteristic of the microelectronic industry have been selected as example. As a first step, a bibliographic study allowed to determine the input data for each of the streams studied (flow rates, composition) as well as the conventional treatment methods used. The conventional treatment processes for the three effluents were then simulated on ProSimPlus®. Depending on the available functionalities of the software (modules, components, thermodynamic model), some processes have been modeled and/or developed on physical, chemical and kinetic data from the literature. In a second step, new treatment streams were proposed for each of the effluents considered. New processes were modeled and then simulated on ProSimPlus®. Depending on the effluent considered, the different couplings refined the treatment thus allowing to reach the discharge limits set in a natural environment or in a sensitive zone to eutrophication, but also to reduce reagents and energy consumption, validating the interest of the couplings. Also, the valorization of by-products has resulted in a significant saving on investment costs
